Narrative of an Expedition into Central Australia. Charles Sturt
undulating and sandy, with clumps of stunted cypress trees, and eucalyptus dumosa scattered over it. Low bushes of rhagodia, at great distances apart, were growing on the more open ground; the soil, consisting of a red clay and sand, only superficially covering the fossil formation beneath it. At 11 a.m. we entered a dense brush of cypress and eucalypti growing in pure sand. Fortunately for us the overlanders had cut a passage through it, so that we had a clear road before us, but the drays sunk deep into the loose sand in which these trees were growing, and the bullocks had a constant strain on the yoke for six miles. We then broke into more open ground, and ultimately reached the river in sufficient time to arrange the camp before sunset, although we had 2½ miles to travel on a S.W. course before we found a convenient place to stop at. Our course during the day having been S.S.E., we had thus been obliged to turn back upon it, but this was owing to the direction the river here takes and was unavoidable. At 6 p.m. the thermometer stood at 55 degrees of Farenheit, the barometer at 30.000, and the boiling point of water by two thermometers with a difference of 2 degrees 212 minutes and 214 minutes, respectively, our distance from the sea coast being about 120 {180 in published text} miles as the crow flies.
It was generally thought in Adelaide that having started so late in the season, I should experience some difficulty in getting feed for the cattle. From my experience, however, of the seasons in the low region through which the Murray flows, I had no such anticipation. The only fear I had, was, that we should be shut out from flats of the river by the floods, as I knew it would be on the rise at the time we should be upon it. To this point, however (and I may add, with few exceptions), we found an abundance of feed, both along the line of the Murray and the Darling, but at our present encampment our animals fared very indifferently, in consequence of the poor nature of the soil. Our tents were pitched at the northern extremity of a long flat, between the river and a serpentine lagoon, which left but a narrow embankment between itself and the stream. The soil of the flat was a cold white clay, on which there was scarcely any vegetation, so that the cattle wandered and kept us about an hour after our appointed hour of starting. There had been a sharp frost during the night, and the morning was bitterly cold. At sunrise the thermometer stood at 29 degrees, the dew point being 43 degrees, and the barometer at 29.700.
When we left this place, our course, for the first three miles, was along the embankment separating the river from the lagoon, and I remarked that although there was so little vegetation on the ground, there were some magnificent trees on the bank of the river itself, which gradually came up to the north-east. At three miles, however, our further course along the flats was checked by the hills of fossil formation, which approached the river so closely as to leave no passage for the drays between it and them. We were, therefore, obliged to ascend to the upper levels, in doing so we were also obliged to put two teams, or sixteen bullocks, to each dray, and even then found it difficult to master the ascent.
Referring back to a previous remark, I would observe that the Murray river is characterised by bold and perpendicular cliffs of different shades of yellow colour, varying from a light hue to a deep ochre. These cliffs rise abruptly from the water to the height of 250 and occasionally 300 feet. They occur first on one side of the river, and then on the other, there being an open or a lightly-timbered flat on the opposite side, with a line of trees almost invariably round it, especially along the river. These flats are backed, at uncertain distances, by the fossil formation, as by a natural inclosure--sometimes it rises perpendicularly from the flats, but more generally assumes the character of sloping hills. The cliffs occasionally extend, like a wall, along the river for two or three miles, and look exceedingly well; but their constant recurrence, at length fatigues the eye. At the point at which we had now arrived this remarkable formation ceases, or, as we are going up the river, I should perhaps be more correct if I said, begins. Above it a long line of hills, broken by deep and rugged stony gullies, and with steep sides, extends to the eastward (that also being the upward course of the river). On gaining the crest of these hills we found ourselves, as usual, on a flat table land, notwithstanding the broken faces of the hills themselves. There was only a narrow space between them, and a low thick brush of eucalyptus to the north. The soil was, as usual, a mixture of clay and sand, with small rounded nodules of limestone. From this ground, the view to the south as a medium point, was over as dark and monotonous a country as could well be described. There was not a single break in its sombre hue, nor was there the slightest rise on the visible horizon; both to the eastward and westward we caught glimpses of the Murray glittering amidst the dark foliage beneath us, but it made no change in the character of the landscape.
We kept on the open ground, just cutting the heads of the gullies, and advanced eight miles before we found a convenient spot at which to drive the cattle down to water, and feed in the flats below, and into which it appeared impracticable to get our drays. I halted, therefore, on the crest of the hills, and sent Flood and three other men to watch the animals, and to head them back if they attempted to wander. In the afternoon we went down to the river, and on crossing the flat came upon the dray tracks of some overland party, the leader of which had taken his drays down the hills, notwithstanding the apparent difficulty of the attempt. But what is there of daring or enterprise that these bold and high-spirited adventurers will shrink from?
I had hoped that the more elevated ground we here occupied, would have been warmer than the flats on which we had hitherto pitched our tents, but in this I was disappointed. The night was just as cold as if we had been in the valley of the Murray. At sunrise the thermometer stood at 27 degrees, and we had thick ice in our pails.
At five miles from this place, having left the river about a mile to our right, we arrived at the termination of this line of hills. They gradually fell away to the eastward and disappeared; nor does the fossil formation extend higher up the Murray. It here commences or terminates, as the traveller is proceeding up or down the stream. A meridian altitude on the hill just before we descended, placed it in lat. 34 degrees 9 minutes 56 seconds, so that we had still been going gradually to the south. At the termination of the hills, the Murray forms an angle in turning sharp round to that point, and after an extensive sweep comes up again, so as to form an opposite angle; the distance between the two being 14 or 15 miles, and from the ground on which we stood the head of Lake Bonney bore E. 5 degrees S., distant six miles.
On descending from these hills we fell into the overland road, but were soon turned from it by reason of the floods, and obliged to travel along a sandy ridge, forming the left bank of a lagoon, running parallel to the river, into which the waters were fast flowing; but finding a favourable place to cross, at a mile distant, we availed ourselves of it, and encamped on the river side. In the afternoon we had heavy rain from the west. During it, Mr. James Hawker, a resident at Moorundi, joined us, and took shelter in our tents. He had, indeed, kept pace with us all the way from the settlement in his boat, and supplied us with wild fowl on several occasions.
We had showers during the night, but the morning, though cloudy, did not prevent our moving on to Lake Bonney, distant, according to our calculation, between four and five miles. To determine this correctly, however, I ordered Mr. Poole to run the chain from the river to the lake. We had seen few or no natives as yet; but expecting to find a large party of them assembled at Lake Bonney, Mr. Eyre went before us with Kenny and Tenbury, leaving Nadbuck and Camboli to shew us the most direct line to the mouth of the little channel which connects Lake Bonney with the Murray, at which I purposed halting. The greater part of our way was through deep sandy cypress brushes, so that the cattle had a heavy pull of it. We reached our destination at 1 p.m., where we found Mr. Eyre, with eight or nine natives, all, who were then in the neighbourhood.
The back-water of the Murray was fast flowing into the lake, which already presented a broad expanse of water to the eye. It was covered with wild fowl of various kinds, and there were several patches of reeds in which they were feeding.
As I purposed stopping for a day or two, to rest the bullocks, I directed Mr. Poole to survey the lake, whilst I undertook to lay down the creek or channel connecting it with the river, in which service I enlisted Mr. Hawker, who had formerly been on the survey, and whose name I gave to the creek on the completion of our work.
Lake Bonney is a shallow sandy basin, which is annually filled by the Murray; and as it rises, so, to a certain extent, it falls with the river, until at length, being left very shallow, it is soon dried up. The Hawker being too small
